2nd question: is there an easy and efficient (cheap) way to get either (i) all fids' connected addresses easily or (ii) changes in connected addresses?

thinking about how to authenticate `msg.sender` on-chain as someone that controls a given `_fid`:
1. query dune for all (fid, verified address) pairs (updated via neynar)
2. generate merkle tree over all w/ keccak256(fid, address)
3. host API and/or publish this somewhere for free

am I missing something

scaling merkle tree could be tough since you'd want real-time data and people could change verified addresses

you could have a separate registry contract that maps `fid -> address[]` and then it's available for everyone

although, scaling that is tough since there's no event for someone revoking a verified address, may still have to query neynar each time to ensure you have fresh data

(spitballing again) maybe a TEE w/ an API endpoint to update it every 12 hours, but someone can pay a fee + fund it to force an update?

extra trust assumption, but that could definitely work

would still need a contract that references the TEE output but that would be a good solution to handle the heavy lifting!
